CITY OF OPELIKA
New Fiber Optic Building for New FTTH Network
Opelika, AL
The City of Opelika is developing a new fiber to the home (FTTH) network to provide both broadband services as well as the ability to monitor and manage their own energy consumption. The FTTH new fiber optic network and new smart grid technology for the network will give residents and businesses access to new high quality broadband voice, data and video services, including lightning-fast Internet access, IPTV and video-on-demand services. Opelika will be the first city in the State of Alabama to build an all fiber optic network and will leverage that infrastructure to enhance economic development and attract new businesses to the community.
CONSTRUCTION CHALLENGE
The $2.6 million project included the complete “Full Turn Key” construction of a 60 foot by 96 foot building that would house the new head-in building and data center building. The scope of work consisted of manufacturing, out-fitting and installation of the building, fencing, power service, dc installation, racking and generators.
PRECAST SOLUTION
The turnkey project involved the manufacturing and complete out-fitting of (2) two Oldcastle Infrastructure # 3096 Precast Concrete Maxi-Mod components to create the required 60 ft x 96 foot building with all specified equipment.
In addition, the fully out-fitted building modules were shipped, installed and made fully functional for the City of Opelika. The # 3096 Precast Concrete Maxi-Mod components were manufactured at our Newnan, GA facility and foundations were installed in the field by our Oldcastle Shelter Solutions Group.
